[英]How to resolve System.Reflection.TargetInvocationException' error?
[英]Web Api response error for get request - System.Reflection.TargetInvocationException - 500 internal server error
當我使用 Postman 調試它時,它可以調用 Web Api 方法。 The controller is scaffolded using option "Web Api 2 Controller with actions, using Entity Framework" in .NET Framework 4.6.1, Web Application Web, Api project.
// GET: api/MovieHallDetails
public IQueryable<MovieHallDetails> GetMovieHallDetails() {
return db.MovieHallDetails;
}
這些是我用 select 和 SQL select 查詢時表中的示例數據:
Id MovieHallId Seats SeatStatus
297 9 1,1 0
298 9 1,2 0
299 9 1,3 0
300 9 1,4 0
I also have many other similar Web Api methods for other tables and I could issues get request and able to get the successful web api response except for this one.
這是我在 Postman 測試時返回的結果
500內部服務器錯誤
塊引用
MovieHallDetails
沒有無參數構造函數。 添加參數構造函數后,問題解決。
